Santiago Aboy Solanes 23834cbdfd [ptr-compr][Turbofan] Adding the DecompressionElimination AdvancedReducer 
After introducing explicit compress and decompress nodes for each load
and store we are left with many nodes that are redundant.

This CL aims to eliminate redundant decompressions and compressions in the
"direct decompression & compression" category.

Also added tests to test the new reducer.
